Description
Technical field
The present invention relates to a kind of solar module packaging adhesive film and preparation method thereof.
Background technology
The effect of ethylene-vinyl acetate copolymer (EVA) glued membrane is to bond with the toughened glass on top and the backboard of bottom after the solar module crystal silicon chip is coated up and down again, thereby protects battery component, assurance generating efficiency.
When carrying out lamination of solar battery components, along with the rising of temperature, the EVA glued membrane is softening, fusing gradually under vacuum condition, fills up the space between cell piece after flowing, then crosslinking curing reticulates molecule under higher temperature, thereby cell piece is closely fixing.In this process, EVA glued membrane telescopicing performance at high temperature has vital impact to the quality of battery component, and this performance embodies by the shrinking percentage index, if shrinking percentage is excessive, can causes the displacement of cell piece even breaks.
It is as follows to produce the principle of shrinking: in the course of processing of EVA glued membrane, the EVA resin reaches melt temperature, carries out unidirectional (vertically) by means of external force and stretches, and makes molecular chain unfold fully and be orientated along external force direction, then fast cooling is freezed the molecular structure of orientation.This forced high-elastic deformation has the memory effect of thermal contraction, and when the EVA glued membrane being reheated draft temperature when above, frozen Molecular orientational structure begins to relax, and shows as on the macroscopic view to begin to shrink; And line speed is faster, and shrinking percentage is larger
Reduce the shrinking percentage of EVA glued membrane mainly from two aspects, the one, use the modified EVA resin, the 2nd, improve film-forming process, the latter is the key of preparation low-shrinkage EVA glued membrane at present.
The adhesiveproperties of EVA glued membrane can affect the permanent stability of solar module operation, therefore requires EVA glued membrane and glass to have good stripping strength, and is general by adding the coupling agents to improve adhesiveproperties at present.When solar module carries out lamination, the reaction of coupling agent and EVA resin generation chemical graft, and and glass generation chemical bonding, make glass with EVA resin bond be in the same place.But coupling agent can produce xanthochromia in long-term outdoor use procedure, and therefore excessive coupling agent will make the ageing-resistant performance of EVA glued membrane reduce, and finally affect the generating efficiency of battery component.
